There are growing electrification possibilities for drive trains and auxiliary machines in construction, commercial and agricultural vehicles. An electric drive train has far fewer parts, especially moving ones, which results in fewer failures and maintenance issues. Using electric rather than hydraulic power in CAV auxiliary machines, including saws, balers and mowers, leads to increased productivity by enabling higher speed and accuracy.

Hybrid designs continue to grow in popularity as well. While they still rely on a combustion engine for parts of the propulsive power, the electric drive delivers torque for peak loads. The advantages range from reduced fuel consumption to braking energy recovery. Electric motors for CAV can also function as a starter-generator, reducing complexity by combining the two parts. Similar to the automotive industry, the generator provides the power needed to operate the vehicle, which always runs electrically. A battery provides an independent energy supply and stores recovered energy. Because electric machines can provide maximum torque at speed zero, they are ideal for heavy-duty applications common to CAV.

Electric CAV solutions

In all-electric drive trains, electric machines controlled by power electronic inverters replace mechanical components. This makes a CAV more reliable and available by further reducing its complexity. CAV often need auxiliary machinery like balers, saws, mowers, rotating brushes or harvesters. Productivity can be improved simply by upgrading these from hydraulic to electric drives.
